You could always order more of the same juice in a much lower nic to 'cut' it.
For example: You have 24mg and you want it to be 12mg, so you'd order 0mg (same mL amount) and mix them together and voila, 12mg with no taste sacrifice.
LOL I've called every, pharmacy and drug store in this town and most don't even know what PG or VG is. (Yes, I used their proper names when asking.)
No one stock it here but, that's Arkansas for ya.
BINGO! Why didn't I think of that? Duh...
Thanks,
